MediciNova Receives Notice of Allowance for New Patent Covering the Combination of MN-166 (ibudilast) and Riluzole for the Treatment of Amyotrophic Lateral Sclerosis (ALS) and other Neurodegenerative Diseases

LA JOLLA, Calif., Jan. 21, 2019 (GLOBE NEWSWIRE) -- MediciNova, Inc., a biopharmaceutical company traded on the NASDAQ Global Market (NASDAQ:MNOV) and the JASDAQ Market of the Tokyo Stock Exchange (Code Number:4875), today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for a pending patent application which covers the combination of MN-166 (ibudilast) and riluzole for the treatment of amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.

Once issued, the patent maturing from this allowed patent application is expected to expire no earlier than November 2035. The allowed claims cover a method of treating a patient diagnosed with ALS, as well as a wide range of other neurodegenerative diseases, with the combination of MN-166 (ibudilast) and riluzole.  Other neurodegenerative diseases covered by this patent include Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, Huntington’s disease, Lewy body disease, motor neuron disease, spinal muscular atrophy, myelopathy, traumatic brain injury, spinal cord injury, and many others.

MediciNova was previously granted a U.S. patent which covers the use of MN-166 (ibudilast) as monotherapy for the treatment of amyotrophic lateral sclerosis (ALS) and it expires no earlier than January 2029.  MediciNova was previously granted three U.S. patents which cover the use of MN-166 (ibudilast) as monotherapy for the treatment of progressive multiple sclerosis including both primary progressive multiple sclerosis and secondary progressive multiple sclerosis.  The first one of these patents expires no earlier than November 2029 and patent term restoration would add 5 years once MN-166 (ibudilast) is approved for progressive multiple sclerosis, extending the patent expiration to November 2034.

Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc., commented, "We are very pleased to receive notice that this new patent will be granted. We believe it could substantially increase the potential value of MN-166 as it could extend the patent life for the ALS indication by almost 7 years compared to our first ALS patent.  In addition, the patent covers a wide range of other neurodegenerative diseases which expands the opportunities for clinical development of MN-166."

About ALS

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. The nerves lose the ability to trigger specific muscles, which causes the muscles to become weak. As a result, ALS affects voluntary movement and patients in the later stages of the disease may become completely paralyzed. Life expectancy of an ALS patient is usually 2-5 years. According to the ALS Association, there are approximately 20,000 ALS patients in the U.S. and approximately 6,000 people in the U.S. are diagnosed with ALS each year.

About MN-166 (ibudilast)

MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule macrophage migration inhibitory factor (MIF) inhibitor and phosphodiesterase (PDE) -4 and -10 inhibitor that suppresses pro-inflammatory cytokines and promotes neurotrophic factors. It attenuates activated glial cells, which play a major role in certain neurological conditions. MN-166 (ibudilast)'s anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical studies, which provide the rationale for treatment of progressive multiple sclerosis (MS) and other neurological diseases such as amyotrophic lateral sclerosis (ALS), substance abuse/addiction and glioblastoma (GBM). MediciNova is developing MN-166 for progressive MS and other neurological conditions such as ALS, substance abuse/addiction, chemotherapy-induced neuropathy, and glioblastoma. MediciNova has a portfolio of patents which cover the use of MN-166 (ibudilast) to treat various diseases including progressive MS, ALS, and drug addiction.
